Hi! I am finding lots a ways to clean the fan on the printer head but not under the laser itself.

  1. What is the fan called?
  2. How do I clean it? It is getting very gunked up and am only able to get the parts I can see.
  3. Do they sell replacements for it?
    Thank you !!

I would like to know some alternatives to this method to clean the assist fan.
This is to dramatic and scary looking , is there a hack like a bent brush.

I thought that the first time I went to do it, but it is not that hard, just trust the directions and follow them.

Reposting Pip’s instructions here as well:

First, you’ll need to obtain a can of 3M Novec Electronic Degreaser, which you can purchase from Amazon or Digikey .

That page will walk you through the cleaning process. Brief summary:

  1. Turn off and unplug your unit and move it outside. Make sure it’s in a location where it has power and Wi-Fi
  2. Using the fan maintenance page, you’ll be able to turn the fan on
  3. Following all manufacturer’s safety instructions from 3M, spray the degreaser into the fan while it’s running for approximately 5 - 10 seconds, or until the fan is clean.
  4. When you’re done cleaning, turn off your unit to stop the fan, and return it to its usual home. You should now see considerably better performance from your exhaust fan!

Please let us know if you have any questions!
